20 Claims.

Our present invention relates to musical supporting arrangements, andmore particularly to automatic musical supports for plates and the like.

It i an object of our invention to provide a musical plate holder whichis constructed so invention mainly consists of a musical supportingarrangement comprising in combination a hollow base, a support mountedon the hollow base slidably in vertical direction, lifting means mountedin the hollow base and engaging the support tending to permanently raisethe same to a predetermined raised position, a spring operated musicalapparatus within the hollow base, and releasing means for the springoperated musical apparatus, the releasing means being actuated by thesupport so as to permit operation of the spring operated musicalapparatus when the support reaches during raising by the lifting meansthe predetermined raised position.

In accordance with a preferred embodiment of our invention, we employ ahollow base which is open at its top, and with a flat support fitting onthe upper rim of the hollow base and provided with an annular flangeengaging the outer face of the hollow base so as to hold the support onthe hollow base slidably in vertical direction.

Furthermore, in order to obtain level positioning of the flat supportmentioned above, We have found it advisable to provide as lifting means,a plurality of spiral springs mounted in the hollow base along the wallof the same and engaging the bottom face of the flat support,permanently tending to lift the same.

The releasing means mentioned above include, in accordance with apreferred embodiment of our invention, a blocking member arranged withinthe hollow base movable between blocking position blocking operation ofthe spring operated musical apparatus, and releasing position permittingoperation of the spring operated musical apparatus, and actuating meansmounted on the support movably together with the same and constructed soas to hold the blocking member in blocking position while the support islocated under the predetermined position, and to permit movement of theblocking member into releasing position when the support reaches duringraising by the lifting means the predetermined raised position.

In order to prevent unintentional operation of the musical apparatusbefore placing the filled plate on the support, or after doing so, dueto shaking of the entire device, we also provide hand operated operatingmeans arranged within the hollow base and projecting outwardly throughan opening in the wall of the base, the hand operated operating meansbeing manually movable between operative position holding the blockingmember in blocking position, and nonoperative position permittingmovement of the blocking member into releasing position.

Of course, it is advisable to provide some kind of moving means, e. g. asmall weight permanently tending to move the blocking memher fromblocking into releasing position.

As stated above, it is of great importance to prevent stopping ofoperation of the musical apparatus after start of the operation byunintentional depression of the plate, e. g. by placing a spoon, knifeor fork thereon. This object is attained by using as actuating holdingmeans, e. g. a holding projection mounted on the support movabletogether with the same, and constructed so as to hold the blockingmember against action of the moving means in blocking position while thesupport is located under the predetermined raised position, and topermanently disengage the blocking member for movement by the movingmeans into releasing position outside of the path of said holding meanswhen the support reaches during raising by the lifting means thepredetermined raised position.

The novel features which we consider as characteristic for our inventionare set forth in particular in the appended claims. The inventionitself, however, both as to its construction and its methods ofoperation, will be best understood from the following description ofspecific embodiments when read in connection with the accompanyingdrawings, in which:

Fig. 1 is an elevational section through our new musical plate holderalong line i-l of Figure 3, with the support in blocking position;

Fig. 2 is an elevational section through the plate holder similar to theone shown in Figure l, with the support in releasing position; and

Fig. 3 is a horizontal section through the plate holder shown in Figures1 and 2, along line 3-3 of Figure 1.

As shown in the drawing, our new plate holder includes as main elements,a hollow base i0, and a ilat support i i slidably mounted on the base Edby means of the annular flange I2 forming part or the support H.

The support H is prevented from sliding on base it by means of slot !3provided in the annular flange l2, and screw l4 passing through slot l3and screwed into the cylindrical wall it of the base Ill.

The base it} is provided also with a bottom Wall it supported by smallcylindrical legs H, as shown in the drawing.

In accordance with our invention, we provide four pins l8 mounted in thesupport ll, extending downwardly into the hollow base if], andprojecting through guiding openings is provided in bottom wall I6 of thebase.

Lifting means consisting of four spiral springs each surrounding one ofthe pins :8 are arranged within the hollow base in the manner shown inFigures 1 and 2. These springs permanently tend to raise the support IIin direction of arrow 2|.

We Wish to stress that it is of great importance that these springs bechosen and adjusted so that they are not strong enough to raise theplate 22 placed on the support I I when filled with food as indicated at23 in Figure l, but that they are strong enough to raise the supporttogether with the base when the same is empty as shown in Figure 2, orthe amount of food has diminished by eating, to a predetermined extent.

Our new arrangement also includes a musical apparatus 21', ofwell-knowntype. This musical apparatus 25; includes a winding member 25,a spring motor 23, a governor 27, a drum 23, and reeds 251 of well-knowntype. The governor El consists of a double vane which is rotated by thespring motor 26 during operation of the musical apparatus.

In order to block operation of the musical apparatus, we provide adouble armed blocking lever including the lever arms 29 and 33. Thisblocking lever is pivoted at 3| to the base and movable between blockingposition shown in Figure 1 with arm 29 in the path of rotation ofgovernor i, and releasing position shown in Figure 2 with arm 29 turnedout of the path of rotation of governor 21.

In order to manually block movement of the musical apparatus, we providethe doubl armed operating lever 32, composed of the operating lever arm33 and the blocking lever arm 34, and pivoted 35 to the bottom wall l6of the base.

The operating lever arm 33 projects outwardly through the opening 36 inthe wall IE or the base and its projecting end 31 is manually turnahieto and fro in direction of arrow 38.

The blocking lever arm 34 is movable by turn-- ing of the projecting end3'! of the lever arm 33 from its non-operative position shown in Figure3 in full lines into operative position shown in dotted lines, and back.In non-operative position, shown also in Figure 2, the blocking lever isadapted to move outside of the path of the governor 2'] while locationof the blocking lever arm 34 in the position shown in dotted lines inFigures l and 3 forces the blocking lever to stay in blocking position.

We wish to note that in order to impart to the blocking lever thetendency to turn from blocking into releasing position, we provide atthe end of the lever arm 30 the weight 39 permanently on (i tending toturn the blocking lever in direction of arrow 40.

The automatic holding means mentioned above include the projection llcooperating with the weight 39 as will be described further below indetail.

our new musical support arrangement operates as follows:

"eIore start of operation the manually operated lever 32 is turned intoits operative blocking position shown in Figures 1 and 3 in dottedlines. Then, the spring motor 28 is wound by means of the winding member25.

Next, the plate 22 is filled with food 23, and placed upon the support Ii. In this position the arrangement is ready for operation.

As the next step, the lever 32 is manually turned into releasingposition shown in full lines in the drawings.

In this position, as evident from Figure 1, the lever arn 3 1 does notblock turning of the blocking lever. This lever is, therefore,theoretically free to turn.

However, it is prevented from such turning by the holding projection llagainst which the weight 33 abuts, while the support H is in itsdepressed position shown in Figure 1. Thus, in this position, themusical apparatus is prevented irom operation.

During eating, the food diminishes in the plate and thereby the samebecomes lighter and lighter.

Consequently, the springs 20 will slowly raise the plate 1.: ii the samereaches the predetermined raiser sition shown in Figure 1. In thisposition, or slightly before attaining this position, the projection liwill be raised to such an extent that the weight 39 can slip past it,drop down, and thereby turn the lever arm 29 of the blocking lever intoreleasing position outside of the path of the governor 21. This willresult in free rotation of the governor, and consequent operation of themusical apparatus.

It should be stressed that our new arrangement is constructed so thatdepression of the plate 22 and support It after disengagement of theprojection and weight 39 will not result in renewed blocking ofoperation of the musical apparatus since the once released weight 39 hasdropped outside of the sphere of influence of the projection a1, andcannot again be engaged by the same.

in order to stop operation of the musical apparatus, it is necessary tomanually move the operating lever 32 back into its blocking positionshown in dotted lines.

It will be understood that each of the elements described above, or twoor more together, may also a useful application in other types ofsugpc-rting arrangements differing from the types described above.

While we have illustrated and described the invention as embodied inmusical plate holders, we do not intend to be limited to the detailsshown, since various modifications and structural changes be madewithout departing in any way from the spirit of our invention.

Without further analysis, the foregoing will so fully reveal the gist ofour invention that others can by applying current knowledge readilyadapt it for various applications without omitting features that, fromthe standpoint of prior art, fairly constitute essential characteristicsof the generic or specific aspects of this invention, and therefore,such adaptations should and are intended to be comprehended within themeaning and range of equivalence of the following claims.
